I agree with your statement regarding adjusting the head clearance for most power and torque. I have ran engine with no shim without any adverse effects ( the engine was very torquey !!! With the pre/post detonation parts, how do you change the squish area, i.e wider or narrower ?

Narrowing is not actually possible in a safe way. By wider or narrow I mean making the dome in the button wider or narrower.
To get it narrower you would need to know the exact area required and get a button made to suit. Just a matter of removing material from the appropriate place on an existing button to get it bigger.

I dont advise anyone to go try doing this unless they know exactly what they are doing and can make the proper calculations and changes to get the desired effect.
